Detecting a quality issue associated with a video stream delivery

A non-transitory computer-readable medium storing instructions that when executed perform operations comprising:

• receiving a manifest of a video stream for presentation via a first client device;
• receiving, from a first cache node, one or more first video stream chunks of the video stream;
• analyzing the one or more first video stream chunks of the video stream;
• analyzing, based upon the manifest, one or more first statuses of one or more second video stream chunks of the video stream, wherein at least one of analyzing the one or more first video stream chunks or analyzing the one or more first statuses comprises:
• determining that a first video stream chunk of the video stream is not associated with a quality issue;
• determining, based upon the manifest, that an arrangement of the video stream provides for a corrective video stream chunk being before a second video stream chunk;
• and
• determining whether the corrective video stream chunk indicated by the manifest as being in the arrangement of the video stream before the second video stream chunk was not received prior to receiving the second video stream chunk indicated by the manifest as being in the arrangement of the video stream after the corrective video stream chunk;
• presenting the first video stream chunk via the first client device based upon determining that the first video stream chunk is not associated with a quality issue;
• transmitting a request, for the corrective video stream chunk indicated by the manifest as being in the arrangement of the video stream, to a second cache node based upon determining that the corrective video stream chunk indicated by the manifest as being in the arrangement of the video stream was not received prior to receiving the second video stream chunk indicated by the manifest as being in the arrangement of the video stream;
• receiving, from the second cache node, the corrective video stream chunk;
• and
• responsive to receiving the corrective video stream chunk from the second cache node, presenting the corrective video stream chunk via the first client device.

A system comprising:

• a processor coupled to memory, the processor configured to execute instructions to perform operations comprising:
• receiving, from a first client device, a request for presentation of a video stream;
• transmitting, to a client-side router associated with the first client device, one or more first video stream chunks, of the video stream, for presentation via the first client device;
• receiving, from the client-side router, a request for a corrective video stream chunk, wherein the request for the corrective video stream chunk is indicative of a first quality issue corresponding to a first video stream chunk having one or more incorrect parameters that are different than video parameters of other video stream chunks of the video stream being presented to the first client device;
• and
• transmitting, to the client-side router, the corrective video stream chunk for presentation via the first client device.
